Can You Drive Up Mt. Lemmon?

There is one paved road up Mt. Lemmon and it is the whole experience: the Catalina Highway, 27.2 miles of continuous climb from the Tucson desert floor to the 9,171-foot summit. The question people actually type into a search box is simpler than that, though. Can you drive it? In what? Is it open? Is it terrifying?

Short version: yes, in an ordinary car, and people do it every day. But there are three caveats that catch visitors out every winter, and one of them will stop your car at a gate.

Can You Drive Up Mt. Lemmon in a Regular Car?

Yes. This is a maintained county highway, not a jeep trail. It is fully paved from the turnoff at Tanque Verde Road all the way to Summerhaven and on past the village. The posted speed limit is 35 mph for essentially the whole climb, and it is enforced.

You do not need four-wheel drive, high clearance, or any special vehicle to drive up Mt. Lemmon in normal weather. Sedans, minivans and rental cars make the trip constantly. The road is plowed by the county when it snows, which is why restrictions during storms are about snow and ice on the surface, not about the road itself being too rough for a normal car.

What you do need

What the highway actually is

The Catalina Highway is also signed SR 391, and it carries the official name Sky Island Parkway - it is designated a National Scenic Byway. About 4.2 miles up you cross the Coronado National Forest boundary, and from there the road is officially the General Hitchcock Highway. The pavement ends at Summerhaven, Arizona, and the final stretch continues past the village to Ski Valley and the summit area.

It climbs roughly 6,782 feet in 27.2 miles: Tucson sits at about 2,389 feet, the summit at 9,171 feet. That is the reason the drive takes longer than the mileage suggests, and the reason the temperature drops as you go. For the full list of what you pass and where, see the Mt Lemmon map and mile markers.

Can You Drive to the Top of Mt. Lemmon?

This is the question behind the question, and the honest answer has a catch. You can drive to the top of Mt. Lemmon - the road reaches the summit area and the pavement runs past Summerhaven to Ski Valley and beyond. But you cannot always drive all the way to the summit, because of a gate.

The winter gate above Ski Valley

Every winter, the road past Mt. Lemmon Ski Valley is gated closed for the season. That gate cuts off the summit and the Mount Lemmon Day Use Area by vehicle. The Forest Service states the road beyond Ski Valley closes in winter, and Observatory Road past Ski Valley is not maintained in winter at all - it closes whenever it is icy.

So the summit you can reach by car depends on the season. In the warm months you can drive to the top. In winter, you can drive up to the gate above Ski Valley - which still puts you at roughly 8,200 feet, well above the snow line most days, with the best of the mountain below you rather than above you.

One thing worth knowing if you are visiting the hotel: Summerhaven sits below that gate. If you are staying in the village, you are already above the closure point that stops day-trippers, which is why the hotel sometimes shifts guest arrival times during storms.

Where the paved road ends

Point on the road	Can you drive there?
Catalina Highway from Tanque Verde Road to Summerhaven	Yes, year round, weather permitting
Summerhaven village (about 8,000 ft)	Yes. This is where the pavement and the businesses are
Ski Valley (about 8,200 ft)	Yes, except during temporary storm closures
The gate above Ski Valley	Closes for the winter season. This is the cut-off point
Observatory Road and the summit area	Summer only. Not maintained in winter

Is the Drive Up Mt. Lemmon Scary?

Some people find it uncomfortable, and it is worth being straight about why rather than pretending otherwise. This is a two-lane mountain road cut into a mountainside, so for much of the climb there is a drop on one side of the pavement. There is guardrail along the exposed sections, the road is curving almost continuously, and at 35 mph the climb takes about 46 minutes with no stops.

What it is not: it is not a cliff road with no barrier, it is not single-lane, it is not gravel, and it is not a road you need nerve or experience to manage. It is a National Scenic Byway - a road built and maintained specifically so ordinary tourists can drive it. Thousands of sedans and rental cars do exactly that every week.

What actually makes people uneasy

• The drop beside the pavement. It is real, and on the upper half of the climb you are high above the valley. This is the main reason people describe the drive as scary.
• No shoulder in places. Where the road is cut into rock there is nowhere to pull off, so if someone behind you is impatient you keep going until a pullout appears.
• Cyclists and blind curves. Combine a road climb with two lanes and limited sight distance and you have to pay attention, particularly on weekend mornings.
• The speed limit feels fast. 35 mph on a curving mountain road with a drop beside it is slower than it sounds and faster than it feels.

How to make it an easy drive

• Drive up in the morning, down in daylight. The descent in the dark on an unfamiliar mountain road is the part visitors underestimate.
• Use the pullouts. Most of the drive is one long overlook. Pull over to look, and let faster traffic past while you are there. Never stop in the road or park on the shoulder.
• Go your own speed within the limit. The road is designed for pullouts to handle slower traffic. There is no prize for holding 35 mph through the tight bends.
• Let a passenger look at the view, not the driver. There are more than a dozen viewpoints on the way up and you can stop at any of them.
• Do the first drive in good weather. Learn the road on a clear day before you attempt it in snow or at night.

How to Drive Up Mt. Lemmon: Step by Step

1. Fill up in Tucson. There is no fuel on the mountain. The closest gas to the base of the highway is at Tanque Verde and Bear Canyon, right before the turnoff. Aim to arrive with at least half a tank - cold weather and idling in a closure both burn fuel faster than you expect.
2. Check the road status. Call (520) 351-3351 from November through March, or any time there is weather in the forecast. If the county has restricted the road, this is where you find out - not at the base.
3. Download offline maps before you leave. Cell coverage on the mountain is spotty. This is the prep step people skip and then regret.
4. Start early. On snow weekends and October fall-colors weekends, the last 27 miles can take twice as long as it should, and once Summerhaven parking fills the sheriff can hold traffic at the base of the highway.
5. Drive for the conditions. The speed limit is 35 mph and it is enforced. Slow down on the curves and use the pullouts to let faster traffic by.
6. Expect a temperature drop as you climb. The mountain runs about 30 degrees cooler than the desert floor, and the change is noticeable over the course of the drive rather than gradually. Bring a layer even in summer.
7. Park in Summerhaven or at a day-use area. Do not park on the shoulder, and do not park on the shoulder to play in the snow on the way up - it blocks plows and emergency vehicles, and it is where cars get hit.

Can You Drive Up Mt. Lemmon at Night?

There is no rule against it and no gate that closes the highway at night, but it is a genuinely different drive, and it is worth deciding deliberately rather than by accident.

• You will see almost nothing. The entire point of the road is the view. At night the vista is a black rectangle and the drive becomes 46 minutes of curves.
• The wildlife is more active. Deer and other animals move near the road at dawn and dusk, and on a dark mountain road you will not see them early.
• The descent is the hard part. Ice forms first in the shaded corners and at elevation. Descending an unfamiliar mountain road in the dark on a cold surface is where the risk concentrates.
• The good news: if your destination is Summerhaven and you are staying there, driving up after dark is completely normal - just take it slowly, arrive with fuel, and expect patches of cold air and possible ice in the shaded sections in winter.

If you specifically want the night, the better version of it is arriving before dark and walking out once the sky goes black. The better version of a night drive is arriving before dark, parking, and then walking out once the sky goes black - Summerhaven is small enough that light pollution is not the problem it is in Tucson, which is what the sunset and night sky guide covers.

Is There a Fee to Drive Up Mt. Lemmon?

No. Driving the Catalina Highway is free. There is no entrance station on the mountain, no gate you pay at, and no fee to drive up and back. It is a public county road.

You pay only if you stop at a developed day-use site along the way. Those run $8 per vehicle per day, or $10 for a weekly pass, and a Coronado National Forest or Interagency pass is accepted in place of the fee. Day-use sites operate 8:00am to 4:30pm Monday to Friday and are closed on federal holidays. There is no overnight camping at day-use sites and no trailers.

Parking in Summerhaven is free, and the village added parking recently - about 75 spaces in the new lot plus 21 spaces on Sabino Canyon Park Road. It still fills on the busiest weekends, which is when the sheriff starts holding traffic at the base.

The Scenic Drive: What You Pass on the Way Up

If you are driving up for the drive itself rather than to get anywhere, these are the stops that matter, in order from the bottom. Full detail on each, including fees and parking, is on the Mt Lemmon map page.

Distance up	Stop	Why stop
Mile 2.6	Babad Do'ag Vista	The first real viewpoint, wheelchair accessible, and free. The name is Tohono O'odham - their name for Mt. Lemmon. No parking 10pm to 6am except for hikers
Miles 4 to 5	Molino Canyon Vista	Short paved trail and a longer gravel path out to canyon viewpoints. You cross the national forest boundary about here
Miles 8 to 9	Thimble Peak and Seven Cataracts	Two pullouts within a mile. Seven Cataracts looks into Willow Canyon, which runs with seasonal waterfalls after rain or snowmelt - best in spring
Mile 14	Windy Point Vista	The classic stop on the drive and the one everybody photographs. Free, day use only. The hoodoo rock formations are here, about 6,600 feet up
Mile 19.9	Palisades Visitor Center	The last developed stop before the village, at (520) 576-6626
Mile 27.2	Summerhaven	End of the pavement, the village, and the food. About 8,000 feet

You drive through five life zones on the way up

The Catalina Highway is one of the few drives anywhere that crosses five life zones in under an hour. You start in saguaro desert at the bottom, climb through oak and grassland, then pine-oak woodland, then the pine and fir forest of the upper mountain. The plants and animals change around you as you go, which is why the drive feels like traveling much further than 27 miles. Our guide to Mt Lemmon hiking trails maps which zone each trail sits in.

Driving Up Mt. Lemmon in Winter

Winter is when the answer to "can you drive up" stops being automatic. Restrictions on the Catalina Highway happen on average 5 to 15 days each winter, and they are usually temporary while plows clear the road.

What the restrictions mean

• Chains or four-wheel drive. When snow is on the highway, generally only vehicles with four-wheel drive, all-wheel drive or chains are allowed past the closure point. It is not the place to test an unfamiliar car.
• The road can close entirely. Heavy snow can shut the highway for a few hours while plows work. It typically reopens the same day.
• The base can close. On the busiest snow weekends the sheriff can close the road at the base of the highway when Summerhaven fills up. If that happens there is genuinely nowhere to park at the top.
• The winter gate. The road above Ski Valley closes for the season, as covered above.

If you are driving up in winter

• Carry chains if you do not have 4WD. They are inexpensive online or at Tucson auto parts stores, and having them means you do not turn around at the gate.
• Tread matters more than anything else. Worn tires are the usual reason a car slides on the climb.
• Arrive and leave in daylight. The drive down in the dark on ice is the part people underestimate.
• Come early. On a snow day, early is the difference between a snow day and a U-turn at the base.
• Check before you commit. The road conditions page covers chains, fuel, packing and parking, and the snow guide covers where the snow actually is.

Sharing the road with cyclists

The Catalina Highway is one of the best-known road climbs in Arizona, and on most good-weather mornings you will share it with bicycles. They are entitled to the lane, they climb slowly, and on a two-lane road with blind curves the safe pass is the one you can see all the way through. If you are the cyclist rather than the driver, our Mt Lemmon road biking guide covers the climb.

Questions People Ask About Driving Up Mt. Lemmon

Can you drive up Mt. Lemmon in a regular car?

Yes. The Catalina Highway is a paved, two-lane county road and a normal passenger car handles it in normal weather. You do not need four-wheel drive, high clearance or any special vehicle. Sedans, minivans and rental cars make the drive constantly. The road is plowed when it snows, which is why winter restrictions are about snow and ice on the surface rather than the road being too rough for an ordinary car.

Can you drive to the top of Mt. Lemmon?

In summer, yes - the pavement runs past Summerhaven to Ski Valley and on toward the summit area. In winter, no: the road above Mt. Lemmon Ski Valley is gated closed for the season, which cuts off the summit and the Mount Lemmon Day Use Area by vehicle. That gate still leaves you at roughly 8,200 feet, and Summerhaven village sits below the closure point, so hotel guests are already above it.

Is the drive up Mt. Lemmon scary?

Some people find it uncomfortable rather than frightening. It is a two-lane mountain road cut into a mountainside, so for much of the climb there is a drop on one side of the pavement, with guardrail along the exposed sections, and the road curves almost continuously. What it is not is a cliff road with no barrier, a single-lane road, or gravel. It is a designated National Scenic Byway, built and maintained so ordinary tourists can drive it, and thousands of sedans do exactly that every week. Driving up in the morning and down in daylight makes it easier for a first visit.

Can you drive up Mt. Lemmon at night?

There is no rule against it and no gate that closes the highway at night, but it is a different drive. You will not see the views the road exists for, wildlife is more active near the road at dawn and dusk, and the descent on a dark, cold surface is where the risk concentrates - ice forms first in the shaded corners at elevation. If your destination is Summerhaven and you are staying there, arriving after dark is completely normal. Take it slowly, arrive with fuel, and watch for patches of ice in winter.

Is there a fee to drive up Mt. Lemmon?

No. Driving the Catalina Highway is free. There is no entrance station, no gate you pay at and no fee to drive up and back, because it is a public county road. You pay only if you stop at a developed day-use site along the way - those are $8 per vehicle per day or $10 for a weekly pass, with a Coronado National Forest or Interagency pass accepted instead. Parking in Summerhaven is free.

Do you need four-wheel drive to drive up Mt. Lemmon?

Not in normal weather. Only when snow is on the highway do restrictions apply, and then generally only vehicles with four-wheel drive, all-wheel drive or chains are allowed past the closure point. If you do not have four-wheel drive, carrying chains is the difference between driving up and turning around at the gate. Tire tread matters more than anything else - worn tires are the usual reason a car slides on the climb.

How long does it take to drive up Mt. Lemmon?

The climb itself is a minimum of about 46 minutes, because the road is 27.2 miles of continuous uphill at a 35 mph speed limit before you add a single photo stop, a slow vehicle or a cyclist. From northeast Tucson that is roughly 45 minutes door to door. From Phoenix, Mesa or Scottsdale plan about three hours. On a snow weekend or an October fall-colors weekend the last 27 miles can take twice as long as it should.

Is the road to Mt. Lemmon paved the whole way?

Yes. The Catalina Highway is fully paved from the turnoff at Tanque Verde Road in northeast Tucson, 27.2 miles to Summerhaven, and the pavement continues past the village to Ski Valley and the summit area. It is also signed SR 391 and carries the official name Sky Island Parkway. About 4.2 miles up you cross the Coronado National Forest boundary, and from there the road is officially the General Hitchcock Highway.

Before You Drive Up

One more thing worth doing before you turn onto the highway: decide whether you are driving up for the day or staying on the mountain. The drive is the same either way, but a day trip means 46 minutes back down at the end of it, and the best parts of Mt. Lemmon - the sunset, the dark sky, the empty morning trails - happen when the day-trippers have gone.
